Frequently Asked Questions

PAYperUSE - Seasonal business

Our business is seasonal, 6 months of the year. Can I split the yearly cost into 2 x 6 month periods?

Better solution for seasonal business is the PAYperUSE. Move away from yearly agreement, with PAYperUSE starts the service at season beginning and stop at end of season. So you pay for 6 months only.

PAYperUSE - Credits bundle

I have a total of 14 units for the entire fleet. I buy 14 black boxes. I run 90 days. That’s 1,260 credits. Can I buy a bundle and split them?

YES, bundle of credits can be shared with the units of the fleet.

PAYperUSE - Credits daily use

Can I use credits on a daily basis?

YES, you can master the credits use by starting and stopping the service based on your daily use or occupancy rate. You can use them during weekend only, or select specific day of the week. See following example with a fleet of 5 units in a week.

PAYperUSE - Credits monthly use

Can I use credits on a monthly basis?

YES, you can master the credits use by starting the service at the beginning of the season and stopping it at the end of the season. See following example with a fleet of 5 units and a season from Apr 1st to September 30th.

PAYperUSE - Credits expiring date

Do these credits expire?

YES, Credits stay valid for 1 year after last Credit use or recharge. So basically every time a credit is used or a recharge occurs life of all credits is extended of 1 year.  Good enough to ensure that spare credits stay valid for the following season. For example, if the season starts May1st and end September 30th, the spare credits will remain until reopening the following May.

BlackBox IP Protection (IP66, IP67...)

What does “IP 65 or 66 or 67” stand for?

IP [first digit] [second digit] code is the International Protection Marking, published by the IEC (International Electrotechnical Commission, standard 60529 – equivalent to the European standard EN 60529) and classifies and rates the degree of protection provided with 2 main digits:

[first digit]  for solid particle protection, against intrusion (body parts such as hands and fingers), dust, accidental contact

[second digit] for liquid ingress protection, against water by mechanical casings and electrical enclosures. 

The digits indicate conformity with the conditions summarized in the table below. The digit 0 is used where no protection is provided. The digit is replaced with the letter “X” when insufficient data has been gathered to assign a protection level.

First Digit Effective against Details


Dust tight No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.
Second Digit Effective against Details


Water jets Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.

Test duration: 1 minute per square meter for at least 15 minutes

Water volume: 12.5 litres per minute
Pressure: 30 kPa at distance of 3 m


Powerful water jets Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.

Test duration: 1 minute per square meter for at least 3 minutes

Water volume: 100 litres per minute
Pressure: 100 kPa at distance of 3 m


Immersion, up to 1 m depth Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).

Test duration: 30 minutes – ref IEC 60529, table 8.

Tested with the lowest point of the enclosure 1000 mm below the surface of the water, or the highest point 150 mm below the surface, whichever is deeper.

Global Multi-Carrier SIM - Network

Does the Global SIM operates in US only or other countries as well?

The SIM included in the Digital Service and already plugged into the BlackBox, is Global, meaning it works in several countries: US, Caribbean, Canada, Europe, South Africa, Australia, NewZealand just to name some of them. Basically the SIM automatically roams across cellular network by country, allowing owners to track and keep control of their assets when sailing to different countries.

What does Multi-Carrier mean?

SIM includeThe Multi-Carrier SIM is interoperable with one or several carriers concurrently in the same area and switch automatically amongst them based on what’s available maximizing the coverage and quality of tracking.

Features - WebPortal and App

Does your offer includes both WebPortal and App?

YES. Both multi-language WebPortal and App are provided with non extra charge. You can access DOTMobile Watercraft Tracking from any fixed or mobile device connected to internet.

Features - Immobilizer

About the immobilizer feature…it’s seem slow to activate compared to other commands.

It’s a critical command which impact on safety. Prior to execute the command DOTMobile interacts with the BlackBox and check if key is off and JetSki, Boat or Yacht is stationary. Only when both conditions are confirmed by the BlackBox, than the command is executed. This is why it takes longer than other commands, but still in a range of 1 or 2 minutes.

Once clicked the immobilizer button, can I stop it prior to its activation?

You can disable the Immobilizer once it has been activated only. Since immobilizer it’s critical for safety, NO unclear conditions are allowed. DOTMobile needs to make sure that the 2 conditions (ON,OFF) are clearly identified, completed and return to you. For this reason it’s possible to state that the Immobilizer is ON when the Blackbox is returning the specific ON message only. Cycle completed. You can now turn OFF the immobilizer, and it’s condition change only after the BlackBox return OFF message.

Features - Speed alarm

When you say alarms when one of my jet skis exceed speed limit, how the maximum speed is set?

You can set the maximum speed limit on DOTMobile WebPortal for each of your jet ski and area.

Features - Geofencing

How many geofences can be set?

Unlimited. Users can pin and drag  endless areas on the map to mark the passage of the JetSki, Boat or Yacht in a specific geographic zone, to control entry in risky areas. Alerts can be sent upon entering and/or leaving the fenced zone areas either to increase security and to improve operations by allowing fleet managers to anticipate preps for next customers once the current one is getting closer to the dock area.

Features - Navionics

When you say Navionics is included, does this mean I can view it via this mapping system on the app or portal or do I need a separate account with them?

YES, Navionics is included. No need of additional operation from your side.
